The article states this from the Bible and it answers the question. "No Arab will pitch his tent there, no shepherd will rest his flocks there” (Isaiah 13:20)? Arabs pitch tents in Arabia, not Rome. The ultimate fulfillment of this verse is the destruction of the last-days Babylon. We know this because the passage speaks about “the day of the Lord” (v. 9) with the “heavens not giving light” (v. 10). This is not historical, but end-times related.

Then we have the Red Sea: “The earth is moved at the noise of their fall, at the cry the noise thereof was heard in the Red Sea” (Jeremiah 49:21). Red Sea is a geographic indicator as to where the last-days Babylon will be located. Look at Mecca on any map and you will see that it sits near the Red Sea. Some may object that Jeremiah 49 is speaking about Edom, which was primarily located in modern-day Jordan. Yet in Ezekiel 25 “Edom” stretches from Teman (Yemen) to Dedan (Saudi Arabia)” (v. 13). Greater Edom included all of the west coast of the Arabian Peninsula.

Notice the description of her destruction: “‘As Sodom and Gomorrah were overthrown, along with their neighboring towns,’ says the LORD, ‘so no one will live there; no man will dwell in it’” (Jeremiah 49:18). "

I am not that knowledgeable on the Biblical History of that area,but when you are talkng about Iran [Shiite] vs Saudi Arabia [Sunni ] you are talking about a religious and territorial dispute that goes on to this day and is still playing out.
